Ingersoll Cutting Tools 6166724 Turning Insert CNMG432MP

Product Description

The INGERSOLL CUTTING TOOLS 6166724 is a solid carbide turning insert with a TiCN (titanium carbonitride) PVD coating, designed for indexable turning operations on CNC lathes and turning centers. It carries the ANSI designation CNMG432MP and ISO code CNMG120408MP TT8080. The insert features an 80-degree diamond (rhombic) shape, a negative rake and negative side clearance geometry, and a 0.031 inch corner radius. The MP chip breaker is rated for roughing and medium machining applications, making this insert a reliable choice for production turning where consistent chip control across a range of depths of cut is required.

This insert is suited for turning steel, stainless steel, superalloys, and titanium in both production and job-shop environments. The TT8080 grade delivers moderate wear resistance balanced with toughness, a combination appropriate for interrupted cuts and variable stock conditions often encountered in aerospace, energy, and general metalworking. It is installed in standard CNMG-style toolholders with a clamp-style holding method and is compatible with any holder accepting an ANSI 432 or ISO 120408 insert seat.

Key Features

• TiCN PVD coating provides moderate wear resistance and toughness across steel, stainless steel, superalloy, and titanium workpieces
• MP chip breaker geometry handles roughing and medium machining, supporting maximum depth of cut up to 0.157 inches
• 80-degree diamond insert shape (Shape Code C) delivers two pairs of cutting edges for 4 total usable edges per insert
• Negative rake and negative side clearance (Clearance Code N, Tolerance Code M) for rigid, stable clamping in CNMG toolholders
• 0.500 inch inscribed circle and 0.508 inch insert length conform to ANSI 432 and ISO 120408 dimensional standards
• PVD coating process preserves sharp edge geometry for tighter tolerances on difficult-to-machine alloys

Compatibility

Designed for use in CNMG-style clamp-type toolholders accepting ANSI Size Code 432 or ISO Size Code 120408 inserts. Compatible with standard negative-rake CNMG insert seats used in external turning, facing, and profiling operations.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer when securing the insert - do not overtighten by hand. Inspect the insert seat and clamp for wear or debris before seating a new insert to ensure proper contact and prevent premature edge failure.
